To all whom it may concern:

Be it known that 1, FRANK E. TEN Even, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Combined Pumps and Starters for Automobiles; and I do hereby declare the following to be a full, clear, and exact'description of the'in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described,reference being had tothe accompanying drawings'whi'ch illustrate an embodiment of the invention selected by me for purposes of illustration, and the said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents a side elevation of my improved air pump and starter showing it operatively connected with the explosion engine of an automobile or other motor vehicle, a portion of the dash board being indicated in section and the location of the air pressure gage and control mechanism for'the hand oper ated control valve being also illustrated. Fig. 2 is a front end elevation of the appa' ratus shown in Fig. 1. Fig. 3 is a rear end elevation of the combined pump and starter detached, drawn to a slightly enlarged scale. Fig. 4 is a top plan view of the combined pump and starter, a portion of the mechanism being indicated in section.

Fig. 9 is a front view of the valve casing with the cover removed, showing the tailed views of the inlet and exhaust valves with which each cylinder of the combined pump and starter is prov ded. Fig. 12 is a detailed sectional view of one of the automatic valves with which each cylinder of the-pump and starter is provided.

The object of my invention is to provide a convertible motor compressor adapted to be operatively connected with an engine, which can be operated by the engine as a pump for the purpose of compressing and storing an or other motor fluid, and which can be operated bysaid compressed motor fluid as a motor for the purpose of starting the explosion engine, that is to say, for the purpose of turning over the engine sufliciently to enable it to operate as an explosion engine under its own power.

The subject matter of this invention is a division of my former application for Letters Patent of the United States filed J um 12, 1914:, and given Serial No. 84 1611.

In the accompanving drawings 1 represents the explosion or internal combustion engine, which in this instance is provided with four'explosion cylinders 2, 3, 4, and 5. Grepresents the crank shaft which is provided witha sprocket wheel 7 by means of which power may be transmitted to the combined pump and compressed fluid motor.

The engine as illustrated in Fig. 1 is mounted on the, forward part of the chassis of an automobile or other motor vehicle, the dash board of which is indicated at 8.

The combined pump and motor is'shown in Figs. 1 and 2 as located at one side of the engine and suitably supported in fixed relation thereto and it comprises a base portion 10 and a plurality of cylinders, three cylinders 11, 12, and 13, being shown in the embodiment illustrated in the drawings. Each of the cylinders is provided with a piston and piston rod of ordinary construction (not shown) operatively connected in the usual manner with a crank shaft 14, which in this instance is provided with a pinion 15 havinga broad face, said pinion being in mesh with a gear wheel 16 mounted on a secondary shaft 17, journaled in bearings in the base 10 of the pump, and extending longitudinally through the same, said gear 16 being connected to the shaftby a key 18 .and beingcapable of sliding longitudinallyon the shaft. Loosely mounted 'on'the shaft is a hub or clutch member '19 provided with a clutch recess 20 to receive a clutch projection 21 which is preferably secured to the gear 16 and upon the. hub or clutch member 19 is secured a sprocket for clutching the Sprocket wheel '22 to the secondary shaft 17, in this instance bymoving the gear wheel 16 endwise on-the shaft 17 to interlock the clutch projection 21 and recess (see Fig. 4) which mechanism includes a cylinder 23 provided .with'a piston v 24 working therein, and piston rod 25 having a shoulder 26 for limiting its outward motion byengagement with the outer end 'of the cylinder, the said piston rod being provided with a yoke 27, engaging an annular groove on the hub of the gear wheel 16,"

and a retracting spring 28 being provided in this instance within the cylinder 23 and surrounding the piston rod 25 for return-' ing the partsto normal position.

. Each of the pump cylinders is provided 'with an inlet valve 30, one of which is shown in detail in F 10, in this instance, provided with a spring seated valve, and the upper end of the pump'cylinders, which are preferably 'formed'as .a single casting, are connected by a delivery. passage 31,-indicated in Fig. 11, and each engine cylinder is provided with an outletvalve indicated at 32 in Fig. 11, provided with spring pressed ball valve which opens to permit the air compressed in the cylinder to pass through the discharge passage 31. The discharge passage '31 communicates with a pipe 33 which is connected through the hand operated control valve hereinafter referred to with a storage tank indicated at 110 in Fig.

from the pump line or discharge passage 31 to'the clutch operating'cylinder 23 (see Fig. 4), for supplying compressed'air to the cylinder 23'to operate the clutch.

'Fromthe foregoing description of the apparatus, itwill be apparent that if the tank is partially charged with air and the control valve hereinafter described is placed in such v a position as to open communication between the pump line'33 and the tank, the

back pressure from the tank will pass to the by-pass. 34 and actuate the piston 24, thus clutching the gear 16 to the engine driven sprocket 22, and if the engine is running,

the pump will be immediately actuated to compress air and force it back into the tank untilthe desired pressureis obtained, when the pump line willbe cut off fromthe tank and the spring 28 will automaticallydis connect the pump fro-mthe engine.

Each of the pump; cylinders is provided with an automatic pressure operated valve 35, one of which is shown in detailin Fig. 12. This valve comprises abody;'36, which may be cast integrallyiwith thepump cyl- 'inder as shown in Figs. 1,2,.3 and 4, or may be formed separately and screwed to the cylinder, as shown in Fig. 12l-provided with a valve seat 37 a needle valve or stem valve 38, adapted'to slide in a suitable guiding means provided in connection with the casing 36, in this instance a threaded sleeve 39,. the valvestem 'being'provided with a piston 40 working in an extension chamber i 41and provided with 'a 'spring 42,.which normally holds thevalve seated; The 'casing36 is provided withan inlet aperture 43 to which a pipe maybe connected,-and the extension chamber is provided below the piston with an inlet 44" to which apipe can be connected, for the purpose of introducing compressed air to operate on the lower face' i its seat. .The relief chambers 45 below'the of the piston 40 and raise the valve off of pistons 40 in all of the-automatic valves 35'' sired way, in this instance by connecting At one end of the pump mechanisml pro-V vide what I term the distributer casing'dndicated at 50 and best shown in Figs. ,5 and are connected with a by pass 46 inany de-. t

7. This casing is conveniently formed on the end of, the pump base and a reduced por- 'tion 14 of the pump crank sh'aftfextends into it and is providedat its end with a closed by a cap 51 and within the casingis a rotary disk valve 52.jwhich is preferably inner face of the'recess formed withincthe l casing 50 and the disk is'providedtwith' a segmental slot 54 and with a segmental recess 55 on its inner face,hav ing a short.

passage 56 extending therefrom and communicating with a central passage 14 in the crank shaft 14, which terminates at one side of the shaft at some convenient point inside'o'f the casing to take care of the ex-v haust when the'pump is used as a'fluid pres V sure motor as hereinafter "described; 7 It will i be understood that the "casing 10 of the pump will be provided with the 1 usual breathing aperture 10'.

- The bottom face of the recesses'iwithin the casing 50, against which the valve disk 52 o 105 pair of apertures 14". *The. casing50 is rotates is provided with threeports, 11 12,

13 from which passages extend which are connected by pipes 11", 12 and 13 respec-' tively, with the casing36 of the automatic valve on the pump cylinders 11, 12, and 13, respectively. The relation of the segmental aperture 54L and the segmental resess 55 of the valve. disk 52 are such that during the rotation of the disk, compressed motive fluid will be admitted to the pump cylinders 11, 12, 13, in rotation, to actuate the same through the aperture 54 while the cylinders will be permitted to exhaust the expanded motor fluid which returns through the same pipes, through the recess 55, to

' the exhaust aperture 14: in the shaft or the 1 sired manner to the atmosphere.

exhaust might be delivered in any other de- The interior of the casing communicates with a lateral passage 57 in a boss 58 on the end of the pump casing, which boss is provided with an inlet aperture 59 connected by a pipe 60 with the compressed air tank through the hand operated control valve hereinafter described, the .pipe 60 beingtermed for convenience, the starter pipe line. The boss 58 is also provided -with a lateral aperture 61 to which is connected the by-pass pipe 46 before referred to, which communicates with the relief chambers of all the automatic valves 35for the purpose of lifting the valves off their seats, as before stated. 7

It will now be seen that if the connection between the pump line 33 and the tank is through the pipe 46 to the reliefchambers of the several automatic valves, thus opening the valves 38 and the motor fluid will also pass'through the passage 57 into the distributer 50 and through the slot 54 and the particular port which is uncovered at the time, to one of the pump cylinders through the automatic valve 35 thereof, thereby imparting motion to the piston in the said valve and starting the pump mechanism which then acts as a 'motor. The rotation of the disk 52 will distribute the compressed fluid to the pump cylinders in rotation as before stated, and the cylinders will exhaust in the manner described so that a rapid rotation of the shaft '14 is effected by the device, acting as a motor. The introduction of compressed air into the pump cylinders as before stated, will efiect automatically the operation of the piston 24: in the cylinder readily understood.

For convenience in applying my invention to the engines of automobiles and other motor vehicles so that the .mechanism can be controlled from a point adjacent to the steering wheel or steering shaft, I employ a controlling valve which is illustrated in detail in Figs. 8 and 9, and which is also shown in Fig. 1. This control valve comprises a valve casing 7 5 which may be conveniently mounted upon the steering sleeve 76 through which the steering shaft 77 provided with the usual steering wheel 78, extends. This casing is provided on the rear face with a removable cover 75 preferably provided with a hollow boss 75 which is connected at one end with a pipe 80 extending to the tank 110, which may be of any desired form or size and which is preferably provided with the usual cut off valve by which it can be hermetically closed, so as to disconnect it. from the pipe line and prevent leakage when the apparatus is left for a considerable time, in order that there always may be a reserve of compressed fluid in the tank. The other end of the passage in the boss 75 is connected by a pipe 81 with a pressure gage 82, which preferably has its dial so located that it can be seen by the operator. The valve casing 75 is provided on its interior face with two ports 83 and 84 communicating with lateral passages which are connected respectively with the starter pipe line and the pump line 33. The valve casing 75 is also provided with an oscillating disk valve 90 which is provided with two apertures 91 and 92 adapted the one to be brought into registration with the port 84, and the other into registration with the port 83, and the disk valve is provided with lateral projections 93 at opposite sides, adapted to engage a pin 94 and stop the valve when it is in one or the other of its operative positions, while in a central position between the two operative positions, both of the ports 83 and 84 will be closed by the solid portion of the disk as clearly shown in Fig. 9. For convenience the oscillating valve disk 90 is provided with a valve stem 95 extending out through the front of the casing and provided with an operating handle 96 and pointer 97 which is placed over the dial 98, and the dial will be marked with an indication for off or neutral position and also for the pump and starter positions. The control valve may be provided with a suitable clamp as indicated at 75 for attaching it to the sleeve 7 6 of the steering head and the shaft 95 may alsob'e supported at its outer end in a suitable bearing 99 provided with aclamp 100 for engaging the steering head andholding the shaft in proper position. I also prefer to employ a spring indicated at 100-inFig. 8 for maintaining the oscillating disk 90 in close engagement with the the'val've casing 75.

The various parts of the apparatus having now been described, it will be understood that if the engine is running and it is desired to compress a quantity of air into the tank, and store the same, the operator will throw the handle 96 to the indicated position for operating the combined pump 7 and starter as a pump, which moves the control valve disk 90 into position to bring the aperture 91 into communication with.

the port '84, the back pressure of air already contained in the tank will immediately exert itself through the pump line 33a's'before described and through, the bypass34 so as to actuate the piston 24 and connect the gear 16 with the sprocket 22, thereby transmitting power from the engine'to the pump shaft 15 and driving the pistons thereof so as to compress airtherein, which is discharged throughthe outlet valves 32, the passage 31 communicating therewith, and back through the pump line 33, ports .84

. and 91. and tank pipe '80, to the tank, the

accummulated pressure being indicated on the gage 82. When the gage reaches the de sired point, say 200 lbs, the operator will move the handle 96 to the neutral position,

thus shutting the pump line at the control valve andthe loss of pressure in the pump line which follows will permit the spring. 28

to disconnect. the clutch mechanism 2021, and disconnect the pump from theengine;

. Supposing that the engine is at rest, and

it is desired to start the engine, the operator will move the handle 96 into the posi tion to bring the valve port 92 into registration with the port '83 and-establish communication between the tank and the starter pipe line 60, and simultaneously establishthe exhaust valves 32 of the pump and the passage 31 to the bypass 34 'andcylinder 23, causing the piston 2 k to act and again connect the gear wheel 16 with the engine.

inner face of:

This enables the pump mechanisinacting as a starter to move the engine shaft 'and start the engine, after which the handle"96 is thrown to the neutral position i and the sup-j ply of compressed 'fiuid :to the pump and engine cylinders is cut off, and the engine will: continue to operateunder its" own power. The spring 28withdraws the clutch member 21 from the recess 20, permitting the combined-pump andz starterv to b brought to 'a condit o ofrest. i

When the combined pump and starter is operated from the engine as before described to compress air into the tank if the operator should neglect to disconnectthe pump, by throwing the controlling valve to neutral position when the desired pressure, say 200 lbs, is reached in the tank, the springs holding the automatic valves 38 on their seats,

which are adjusted to resist any pressure below that desired in the tank, will thereafter yield and permit an escape of compressed air from the pump cylinders. When this occurs the lifting of the valves, 38, off of their seats, 37, will establish communication through the passage, 43, of each valve casing and the connecting pipes or passages, 11?, 12 'and l3 with the distributerports 11 12*, and 13 and as these several ports are brought into communication with the exhaust recess, 55, of the rotary distributor valve the compressedair will escape through the said recess and pas sage, 56, to the exhaust passage, 14:, in the pump shaft, and thence to the atmosphere.
